Udonga lweMembrane, olukwabizwa ngokuba ludonga olupholisa inwebu ngamanzi, lusebenzisa iityhubhu kunye nentsimbi ecaba edityanisiweyo ukwenza ikhusi letyhubhu, emva koko amaqela amaninzi ezikrini zetyhubhu adityaniswa kunye ukwenza ulwakhiwo lodonga lwenwebu.
Ziziphi iingenelo zesakhiwo sodonga lwe-membrane?
Udonga olupholileyo lwe-membrane luqinisekisa ukuqina okuhle kwesithando somlilo.Kwiibhoyili zoxinzelelo olubi, inokunciphisa kakhulu i-coefficient yokuvuza komoya yesithando somlilo, iphucule iimeko zokutsha eziko, kwaye yandise indawo esebenzayo yokufudumeza ngemitha, ngaloo ndlela igcina ukusetyenziswa kwentsimbi.Iindonga zeMembrane zisetyenziswa kakhulu kwi-membrane eludongeni lwejenereyitha zomphunga.Zineenzuzo zesakhiwo esilula, ukugcina insimbi, ukugquma okungcono kunye nokuqina komoya.
Inwebu eludongeni ityhubhu yekhusi inyibilika igesi esebenzayo kakhulu ekhusela umgca wemveliso we-welding oluzenzekelayo yeyona inwebu ephezulu yehlabathi ityhubhu yokuvelisa ubuchwepheshe kunye nezixhobo, ukusuka kwityhubhu yokulayishwa, ukuqaqanjiswa kwentsimbi ecaba, ukugqiba, ukulinganisa, ukuwelda, njl. Qonda ulawulo oluzenzekelayo.Imipu ye-welding ephezulu nasezantsi inokudityaniswa ngaxeshanye, i-welding deformation incinci, kwaye akukho mfuneko yokulungiswa emva kwe-welding, ukwenzela ukuba imilinganiselo yejometri yepaneli ye-tube ichanekile, umgangatho we-fillet weld ugqwesile. ubume buhle, isantya se-welding sikhawuleza, kunye nokusebenza kakuhle kwemveliso kuphezulu.
Ijenereyitha yomphunga yeNobeth inomgca wokuvelisa inwebu ehambele phambili, kwaye iziko lithatha itekhnoloji yokutywinwa kodonga olupholileyo lwamanzi.Kwinkqubo yokulungiswa kodonga lwe-membrane, i-welding ephindwe kabini ngaxeshanye isetyenzisiweyo, ukwenzela ukuba i-workpiece ifudunyezwe ngokulinganayo kwaye iphaneli yetyhubhu iyancipha;kwakhona kuphelisa isidingo sokujika kwi-welding, ukunciphisa umthwalo wokulungisa ukulungiswa kwe-deformation emva kwe-welding yemveliso, kunye nokuphucula kakhulu ukusebenza kwemveliso.Ke ngoko, uninzi lweejenereyitha zodonga lwe-membrane luthunyelwa ludityaniswe ngokupheleleyo ukusuka kumzi-mveliso, lwenza uthutho kunye nofakelo lube lula kakhulu, kwaye isixa sofakelo kwisiza esifunwa ngumsebenzisi sincitshiswe kakhulu.
(1) Udonga olupholileyo lwe-membrane lunempembelelo epheleleyo yokukhusela eludongeni lwesithando somlilo.Ngoko ke, udonga lwesithando somlilo lufuna kuphela izinto zokugquma endaweni yezinto eziphikisayo, ezinciphisa kakhulu ubukhulu kunye nobunzima bodonga lwesithando somlilo, lwenza lula udonga lwesithando somlilo, kunye nokunciphisa iindleko zodonga lwesithando somlilo.Ubunzima bebhoyila bubonke.
(2) I-membrane eludongeni olupholileyo lwamanzi lukwanayo nokuqina komoya okulungileyo, luyakwazi ukuziqhelanisa neemfuno zokutsha koxinzelelo olulungileyo kwibhoyila, aluqhelekanga kwi-slagging, lunokuvuza kancinci komoya, lunciphisa ukulahleka kobushushu, kwaye luphucule ukusebenza kakuhle kwe-thermal. kwibhoyila.

(4) Iibhoyili ezisebenzisa izakhiwo zodonga lwe-membrane zilula kwaye zilula ukuzigcina, kwaye ubomi benkonzo yebhoyili bunokuphuculwa kakhulu.
I-Welding ye-welding ye-fillet panel ye-fillet welds
I-tube screen welding indlela ye-membrane eludongeni umbhobho wokukhanya kunye nesakhiwo sentsimbi esicaba.Inkqubo yokuwelda esetyenziswa kwinwebu eludongeni umbhobho wokukhanya kunye nesakhiwo sentsimbi esicaba ikakhulu ibandakanya oku kulandelayo:
1. Ukunyibilika ngokuzenzekelayo kwerhasi esebenzayo ekhusela ukuwelda
Ukubunjwa okuxubileyo kwegesi yokukhusela (Ar) 85% ~ 90% + (CO2) 15% ~ 10%.Kwisixhobo, umbhobho kunye nentsimbi yesicaba zinyanzeliswa ngama-roller aphezulu nangaphantsi kwaye ahanjiswe phambili.Imipu ye-welding emininzi ingasetyenziselwa ukunyuka nokuhla.Ukuwelda kwenziwa ngaxeshanye.
2. Ukuwelda kwe-arc ngocingo olucolekileyo
Esi sixhobo yindawo yokusebenzela yesakhelo esisigxina.Isixhobo somatshini sinemisebenzi yombhobho wensimbi kunye nokubekwa kwentsimbi yesicaba, i-clamping, isondlo, i-welding kunye nokubuyiswa kwe-flux ngokuzenzekelayo.Ixhotyiswe ngokubanzi ngemipu ye-welding e-4 okanye e-8 ukugqiba izikhundla ezi-4 okanye ezi-8 ezithe tyaba ngaxeshanye.Welding of fillet welds.Le teknoloji ilula ukusebenza kwaye ayinayo imfuneko ephezulu kumphezulu wombhobho kunye nentsimbi.Nangona kunjalo, inokudityaniswa kuphela kwicala elinye kwindawo ethe tyaba kwaye ayikwazi ukufikelela kwi-welding ngaxeshanye phezulu nasezantsi.
3. Semi-automatic igesi yentsimbi arc welding
Xa i-welding ngale ndlela, iphaneli ye-tube kufuneka ifakwe i-welded kwaye igxininiswe kuqala, kwaye idityaniswe ngokusebenza ngesandla kwi-welding gun.Le ndlela ye-welding ayikwazi ukudibanisa iindawo eziphezulu kunye nezisezantsi ngaxeshanye, kwaye kunzima ukufezekisa i-welding eqhubekayo kunye neyunifomu yeemipu ezininzi ze-welding, ngoko ke kunzima ukulawula i-welding deformation.Xa i-semi-automatic gas metal arc welding isetyenziselwa ukudibanisa ipaneli yombhobho, ingqalelo kufuneka ihlawulwe ekukhetheni okufanelekileyo kokulandelelana kwe-welding ukunciphisa i-welding deformation.I-fillet welds yokutywina isinyithi esisicaba kwiindawo zokuvuleka kwendawo kwiipaneli zetyhubhu, kunye ne-welds ye-fillet yeepaneli zetyhubhu ezikhethekileyo ezifana ne-ash hoppers ebandayo kunye ne-burner nozzles, zihlala zifakwe kwi-semi-automatic metal arc welding.
Inwebu eludongeni ityhubhu yekhusi inyibilika igesi esebenzayo kakhulu ekhusela umgca wemveliso we-welding oluzenzekelayo yeyona inwebu ephezulu yehlabathi ityhubhu yokuvelisa ubuchwepheshe kunye nezixhobo, ukusuka kwityhubhu yokulayishwa, ukuqaqanjiswa kwentsimbi ecaba, ukugqiba, ukulinganisa, ukuwelda, njl. Qonda ulawulo oluzenzekelayo.Imipu ye-welding ephezulu nasezantsi inokudityaniswa ngaxeshanye, i-welding deformation incinci, kwaye akukho mfuneko yokulungiswa emva kwe-welding, ukwenzela ukuba imilinganiselo yejometri yepaneli ye-tube ichanekile, umgangatho we-fillet weld ugqwesile. ubume buhle, isantya se-welding sikhawuleza, kunye nokusebenza kakuhle kwemveliso kuphezulu.
